Mainly quiet, at most making a cross between a whimper and a moan as I orgasm. I've had some real screamers under me, though, which at times can be awkward depending upon location & circumstances. But I do like a guy who makes some kind of sound, not totally silent, maybe happy murmurs, sighs & gasps, to give some feedback to guide me about what he's liking.
I've also had guys who wanted me to talk "dirty" to them, to keep up a constant graphic narrative of what I was doing to them, sometimes with a little domination thing going on. I'm not good at doing that, and find it a distraction. Likewise some guys have wanted to talk to me non-stop, and I'm not comfortable when they expect me to be responding back to them the whole time, giving the responses they wanna hear. I don't think sex needs a script.
PS: I like your current main pic.
